SPECIFICATION forming part of Letters Patent No. 403,198, dated May 14,1889.

Application filed December 21, 1888. Serial No. 294,258. (No model.)

To all whom it may concern:

Be it known that I, FRED LACEY, of Adams, in the county of Berkshire andState of Massachusetts, have invented a new and Improved Loom Attachmentfor Weaving Center Selvages, of which the following is a full, clear,and exact description.

This invention relates to an attachment for looms upon which splits ormore than one width of cloth are woven at the same time, the object ofthe invention being to produce center selvages; and to the end named theinvention consists in the construction and combinations of partshereinafter fully explained, and specifically pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar figures and letters of referenceindicate corresponding parts in all the views.

Figure 1 is a face view of my attachment, the parts being represented asthey appear when the shed is closed. Fig. 2 is a similar view, theparts, however, being represented as they appear when theneedle-carrying slide has been tilted to the left. sectional view online :23 0c of Fig. 1. Fig. 4 is a face view of the attachment, theparts being represented as they appear when the needle-carryin g slidehas been tilted to the right. Fig. 5 is a similar view, the parts,however, being represented as they appear after the slide has beenraised to its upper position and the shed has been formed. Fig. 6 is aside view of the attachment, representing it as it appears'when the shedhas been formed, the parts being in the position in which they are shownin Fig. 5. Fig. 7 is a face view of my attachment, representing it as itappears when arranged for use in connection with a loom upon whichdouble-backed fabrics of more than one width are woven. Fig. 8 is a viewrepresenting a portion of a piece of fabric in which there are centerselvages formed by means of my attachment. Fig. 9 is a view of a fabricwherein three warp-threads instead of two are bound by thewhipping-thread. Fig. 10 is a diagram of the double-backed fabric suchas is operated upon by the construction shown in Fig. 7, and Fig. 11 isa view of the weave produced by my attachment when Fig. 3 is a crosssuchattachment is employed to weave corded stripes into the body of afabric.

In the drawings, 10 represents a stiff metallic plate that is arrangedfor rigid connection with the loom-frame, the plate being placed back ofthe loom-lay and in front of the harness, a supplemental casting beingat times necessary in order to secure a proper adjustment of the plate,said casting being bolted to the frame and the plate being bolted to thecasting.

It will be readily understood that the form of the casting abovereferred to would vary with the form of loom upon which my attachment isto be employed.

Near the lower end of the plate 10 there is formed a long slot, a,through which there is passed a bolt, 11, said bolt passing through anaperture formed in a slide, 12, there to engage a nut, 13. To the upperend of the slide 12 there are secured needles 14 and 14., while to thelower portion of the slide there are ad-' justably connected stop-plates15 and 15, said plates being provided with lugs or cars 16, whichoverlap the plate 10, the plates 15 and 15 being connected to the slide12 by a setscrew, 17 which said set-screw passes through slots 1),formed in the plates, the arrangement being such that the plates 15 and15 may be moved outward or in ward and their lugs or cars 16 carriedtoward or from the side edges of the plate 10. Cords 18 and18 areconnected to projections 19 and 19, which extend laterally from theslide 12, said cords in turn being connected to the selvage harnesses orlevers, as will be readily understood.

The slide 12 carries a spool, 20, upon which there are wound twothreads, 0, that are passed through the eyes of the needles 14 and 14.,and in order that a proper and uniform tension may be at all timesimparted to the, threads I arrange a spring, 21, in a position such thatit will bear upon the inner face of the thread wound upon the spool, thespring being provided with an adj usting-screw, 22, whereby its tensionmay be regulated.

By mounting the spring 21 so that it will bear upon the thread insteadof upon the spool proper I secure a uniform tension upon the thread 0,inasmuch as the pressure of the spring decreases as the leverage of thethread decreases-that is, as the thread unwinds so i that the face ofthe roll approaches the axis of the spool the leverage necessarilydecreases and the pressure exerted by the spring also decreases. Thewarp-threads upon the outside of the inner edges of the two pieces ofcloth that are woven together are passed through slots 5 and 5, formedin the plate 10.

When the shed is closed, the parts of my attachment will be in theposition in which they are shown in Fig. 1. Then if the cord 18 be drawnupon the slide 12 will be tilted to the position in which it is shown inFig. 2, whereby the point of the needle 14 will be carried to the leftof the slot 5, and the point of the needle 1a will be carried to theleft of the slot 5that is, to a point between the slots 5 and 5, asshown in Fig. 2. Then if the cord 18 be drawn upon as the shed is formedthe slide 12 will be raised and the threads 0 carried up with the upperwarpthreads and to the left of the threads which pass through the slots5 and 5. After the shuttle has passed through the shed and the pick hasbeen formed the tension upon the cord 18 is relaxed and the slide 12will lower to the position in which it is shown in Fig. 1.

Upon the formation of the next shed the cord 18 is drawn upon, and asthe cord 18 is so drawn upon the slide 12 will be moved first to theposition in which it is shown in Fig.

4, and then to the position in which it is shown in Fig. 5-that is, to aposition such that the needle 11 will be to the right of the slot 5, andthis alternate movement being continued will result in the weave shownin Fig. 8, the binding-cord being carried as represented in said figure.As the picks are formed they are out.

If desired, three or more warp threads or yarns might be passed throughthe slots 5 and 5*,01', if desired, the cords 1S and 18, instead ofbeing drawn upward alternately, might each be drawn upward twice insuccession, or each three or more times in succession. (See Fig. 9.)

From the above description it will be seen that the tilting of the slide12 can be readily controlled by properly adjusting the plates 15 and 15.

If double-backed fabrics are to be woven, I would connect a slide, 12,to the upper end of the plate 10, this slide being drawn back to itsnormal position by a spring, 30. In other respects the slide 12 wouldoperate exactly as would the slide 12.

Although the attachment above described is designed more especially foruse in the formation of inner or center selvages, still the attachmentcould be very successfully employed in the formation of corded stripesthrough the body of a fabric. (See Fig. 11.)

Having thus described my invention, 1 claim as new and desire to secureby Letters Patent 1. The combination, with the longitudinally-slottedplate adapted to be connected to a loom-frame, of a tiltingneedle-carrying slide, a bolt extending through said slide and slot, andlaterally-extending stops projecting from opposite sides of the slideand embracing the said plate to limit the tilting of the slide withoutinterfering with its sliding movement, substantially as set forth.

2. The combination, with the slotted plate, of the needle-carrying slidethereon, having spool-bearings, substantially as set fort-h.

3. The combination, with the plate 10, having a longitudinal slot, at,and parallel threadslots 5 5, of the tilting needle-carrying slide,through which and the said slot at a bolt, 11, passes, and thelaterally-adjustable stops on the slide embracing the sides of theplate, and the lugs or cars 19 19 projecting from opposite sides of theslide for connection with selvage harness or levers, substantially asset forth.

1. The combination, with a slotted plate arranged for connection with aloom-frame, of a tilting needle-carrying slide mounted to movevertically upon said plate and adapted to carry a spool, and stop-platescarried by the slide, substantially as described.

5. The combination, with a slotted platcarranged for connection with aloom-frame, of the needle-carrying slide mounted to move vertically onsaid plate and arranged for connection with a harness, stop-platescarried by the slide, spool-bearings upon the slide, and a springprojecting between the said bearings, substantially as described.

6. The combination, with a plate, 10, ar-.

ranged for connection with a loom-frame and formed with slots 5, 5, anda, of a slide, abolt connected to the slide and passing through the slotat, needles carried by the slide, plates 15 and 15, formed with lugs orcars 16, and a set-screw by which said plates are connected to theslide, the slide being arranged for connection with selvage harnesses orlevers, substantially as described.
